[PATCH 12/12] grub-shell: Update qemu UEFI firmware names to be more generic

[Glenn Washburn <development@efficientek.com>]

The current qemu firmware paths for arm-efi and arm64-efi are hardcoded
and not available on Ubuntu/Debian. Make these paths relative and basenames
generic. The idea is that regardless where or what names firmware images
are installed under they can be copied and renamed into a temporary
directory. Then use the -L argument to qemu to point to that directory.

For convenience, the GRUB source directory which build grub-shell will be
added to the list of firmware paths that qemu will search. So all that is
needed is to copy the firmwares to the source directory with potential
renames.
